It is the responsibility of the programmer to ensure that

- the format string is valid,
|
|
- the format string does not use %ls or %lc directives, and
|
|
- all widths in the format string and passed as arguments are >= -INT_MAX

|

- [EINVAL] invalid format string,

- [EILSEQ] error during conversion between wide and multibyte characters,
|
|
- [EOVERFLOW] some specified width is > INT_MAX,
|
|
cannot occur.
|
|
|
|
Formatting takes place in the C locale, that is, the decimal point
|
|
used in floating-point formatting directives is always '.'. */
